Calculated the gravitational potential energy of a 93.0 kg sky diver who is 550 m above the ground

1 answer:

4 0

Equation for Gravitation Potential Energy...
GPe = m·g·h
where m = mass in kg = 93.0 kg
g = force of gravity = 9.81 m/s²
<span>h = height in meters = 550m
</span>
GPe = mgh
GPe = (93)(9.81)(550)
GPe = 501781.5 Joules (J)
GPe = 5.02 x 10⁵ J (rounded & in scientific notation)

Therefore, the gravitational potential energy of a person of mass 93.0kg who is 550m above the ground is GPe = 501781.5 Joules (J)

Hope this helps!

How much energy in Joules (J) would an electric heater that draws 9.5 A when connected to a 120 V supply use if the heater were

leonid [27]

<h2>Energy used by heater is 8.21 x 10⁶ J</h2>

Explanation:

Energy = Power x Time

Power = Voltage x Current

Voltage = 120 V

Current = 9.5 A

Power = Voltage x Current

Power = 120 x 9.5 = 1140 W

Time = 2 hours = 2 x 60 x 60 = 7200 s

Energy = Power x Time

Energy = 1140 x 7200

Energy = 8208000 J

Energy used by heater is 8.21 x 10⁶ J

Explain why the elements of the same group exhibit the same chemical behavior

ElenaW [278]

Answer:

All the elements of a period have similar chemical properties because they have the same number of valence electrons in their outermost shell. Their atoms have the same number of electrons in the highest occupied energy level

A motorboat heads due east at 16 m/s across a river that flows due south at 9.0 m/s. a.) What is the resultant velocity of the b

alukav5142 [94]

Answer:

a)V=18.35 m/s (South -East)

b) t =7.41 m/s

c)D= 66.70 m

Explanation:

Given that

Velocity of boat in east direction = 16 m/s

Velocity of river = 9 m/s

a)The resultant velocity V

$V=\sqrt{16^2+9^2}\ m/s$

V=18.35 m/s (South -East)

We know that

Distance = Velocity x time

Lets t time takes to cross the river

136 = 18.35 x t

t =7.41 m/s

The distance covered downstream

We know that

Distance = Velocity x time

t= 7.41 s

D= 7.41 x 9 m

D= 66.70 m
